This is an upgraded version of the original Aero ProDrive with the exact same technical specifications, but with the addition of Babolat's latest Cortex vibration filtration system for improved ball feel and comfort. It maintains APD's good hitting feel and topspin performance. It combines the AERO frame and the PD head design to achieve the unity of ball feel, spin and maneuverability.
Baseline players can find that the speed, spin and precision of the new apd shots are very good; In front of the net, on the other hand, he showed good maneuverability and maintained good stability on the surface, and his volleys were full of power and the ball was very noticeable when touching the ball. And the power and spin of this racquet make your tee a lot of fun. APD Cortex's comfortable sweet spot and powerful power make it an excellent choice for players of all skill levels.
Comparison: The material is the same, both are high modulus graphite high-density carbon fibers. The pat face is smaller. However, the APD has a Cortex vibration filtration system. You two usually play ball, you can change the experience.
